解析muilti维JSON数组到Python [英] Parsing muilti dimensional Json array to Python

问题描述

我在我头上，试图解析JSON我第一次和处理多维数组。

I'm in over my head, trying to parse JSON for my first time and dealing with a multi dimensional array.

{
  "secret": "[Hidden]",
  "minutes": 20,
  "link": "http:\/\/www.1.com",
  "bookmark_collection": {
    "free_link": {
      "name": "#free_link#",
      "bookmarks": [
        {
          "name": "1",
          "link": "http:\/\/www.1.com"
        },
        {
          "name": "2",
          "link": "http:\/\/2.dk"
        },
        {
          "name": "3",
          "link": "http:\/\/www.3.in"
        }
      ]
    },
    "boarding_pass": {
      "name": "Boarding Pass",
      "bookmarks": [
        {
          "name": "1",
          "link": "http:\/\/www.1.com\/"
        },
        {
          "name": "2",
          "link": "http:\/\/www.2.com\/"
        },
        {
          "name": "3",
          "link": "http:\/\/www.3.hk"
        }
      ]
    },
    "sublinks": {
      "name": "sublinks",
      "link": [
        "http:\/\/www.1.com",
        "http:\/\/www.2.com",
        "http:\/\/www.3.com"
      ]
    }
  }
}

这是分为3个部分，我的第一维静态数据（秘密，分，链接），我需要得到作为单独的字符串。

This is divided into 3 parts, the static data on my first dimension (secret, minutes, link) Which i need to get as seperate strings.

然后，我需要每个书签收藏，它没有固定的名字一本字典，所以我需要他们的名称和链接/每个书签的名字。

Then I need a dictionary per "bookmark collection" which does not have fixed names, so I need the name of them and the links/names of each bookmark.

再有就是单独sublinks这是永远不变的，我需要在一个单独的字典中的所有链接。

Then there is the seperate sublinks which is always the same, where I need all the links in a seperate dictionary.

我念叨解析JSON，但大部分的东西，我觉得是一个简单的数组投入1字典。
没有人有任何好的技术来做到这一点？

I'm reading about parsing JSON but most of the stuff I find is a simple array put into 1 dictionary. Does anyone have any good techniques to do this ?

推荐答案

您解析JSON后，将结束与Python字典。因此，假设上述JSON是在一个名为input_data字符串：

After you parse the JSON, you will end up with a Python dict. So, suppose the above JSON is in a string named input_data:

import json
# This converts from JSON to a python dict
parsed_input = json.loads(input_data)

# Now, all of your static variables are referenceable as keys:
secret = parsed_input['secret']
minutes = parsed_input['minutes']
link = parsed_input['link']

# Plus, you can get your bookmark collection as:
bookmark_collection = parsed_input['bookmark_collection']

# Print a list of names of the bookmark collections...
print bookmark_collection.keys() # Note this contains sublinks, so remove it if needed

# Get the name of the Boarding Pass bookmark:
print bookmark_collection['boarding_pass']['name']

# Print out a list of all bookmark links as:
#  Boarding Pass
#    * 1: http://www.1.com/
#    * 2: http://www.2.com/
#  ...
for bookmark_definition in bookmark_collection.values():
    # Skip sublinks...
    if bookmark_definition['name'] == 'sublinks':
        continue
    print bookmark_definition['name']
    for bookmark in bookmark_definition['bookmarks']:
        print "    * %(name)s: %(link)s" % bookmark

# Get the sublink definition:
sublinks = parsed_input['bookmark_collection']['sublinks']

# .. and print them
print sublinks['name']
for link in sublinks['link']:
    print '  *', link
